Abstract:
Objective:To explore changes of peripheral blood levels of C reactive protein (CRP)and matrix metallo-proteinase-9 (MMP-9)in patients with coronary heart diseases (CHD)and percutaneous coronary intervention (PCI),and analyze their relationship with patients'prognosis.Methods:A total of 278 CHD patients undergoing PCI in our hospital from Jul 2009 to Apr 2011 were regarded as PCI group;another 234 CHD patients not receiving PCI were enrolled as CHD control group.According to results of coronary angiography,PCI group was further di-vided into single-vessel (n=143),double-vessel (n=92)and triple-vessel disease group (n=43).Changes of CRP and MMP-9 levels were compared between two groups in different time,and the relationship among these two in-flammatory factors and coronary disease,its prognosis was analyzed.Results:Compared with on admission,there were significant rise in levels of CRP [(2.43±0.62)mg/L vs.(2.87±0.73)mg/L,(2.98±0.87)mg/L]and MMP-9 [(12.63±2.68)ng/ml vs.(14.62±3.49)ng/ml,(19.62±4.63)ng/ml]in PCI group on 24h and 48h after PCI,P <0.05~<0.01;there were no significant difference in CRP and MMP-9 levels between on admission and 14d after PCI,P >0.05;The more severe coronary lesion was,the higher CRP and MMP-9 levels were,CRP and MMP-9 levels of triple-vessel group [(2.51 ±0.64)mg/L,(14.67±2.97)ng/ml]were significantly higher than those of single-vessel group [(1.83±0.51)mg/L,(9.68±1.42)ng/ml]and double-vessel group [(2.17±0.59) mg/L,(11.62±2.19)ng/ml],P <0.05~<0.01;incidence rates of cardiovascular events in patients with CRP≥3 mg/L and MMP-9≥15 ng/ml (33.3%,29.1%)were significantly higher than those of patients with CRP <3 mg/L and MMP-9<15 ng/ml (16.1%,18.2%)respectively,P <0.05 both.Conclusion:Serum levels of CRP and MMP-9 significantly rise in CHD patients on 48h after PCI,and their increasing level is related with extent of coronary ar-tery lesion and prognosis.
